Agfapan APX 100 and Rodinal

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

I am still getting too contrast negatives when I am developing APX 100 in Rodina (1+50) 17 minutes (20C). I have heart that it is possible to develop APX with Rodinal diluted 1+100. Can anyone suggest time for this kind of developing? I would like to have a bit less contrast negatives with good grain.

Thanks for your suggestion

Shorten the time with two or three minutes for normal contrast. The times recommended by Agfa are too long. Another suggestion is that you expose APX 100 at 50 Asa and develop in Rodinal 1+50 for 10 minutes. You will get finer grain and a longer tonal range.

Agfa seems to admit this time is too long and in the most recent data sheets they have kept the 17 minutes for 1+50 but at a EI of 160. I develop APX100 15 minutes in rodinal 1+60 and get very good results with it. I developed once APX100 in rodinal 1+100 for 20 minutes and I t gave negatives which were too thin. According to agfa, it is good for EI 64 which seems correct to me but negatives will be soft. I develop APX25 and PanF+ in rodinal 1+100 during 20 minutes with very nice results. Greetings, Frederik

I develop APX 100 using Rodinal (1:50) for 12 minutes at an EI of 100, and for 8 minutes at an EI of 50 (both at 68 degrees F).

I would start by modifying your agitation, since this will decrease the contrast and keep the grain, which requires time, even in Rodinal at 1:100. Generally, big grain, and standard contrast can happen with a compensating technique...hope this is actually helpful?

...by 'actually helpful', I meant I hope what I wrote is intelligble and relevent, not implying anything of the other answers, sorry...shawn
